"ros2: command not found" after I source install/local_setup.bash #44

Hi,

I'm ruuning the Nav2 + slam_toolbox Example, and I'm at "Start RViz in the Docker container" - "(Optional) Launching ROS2 components manually" stage.

After I $ _source ros2_docker/colcon_ws/install/localsetup.bash(or $ _source ros2_docker/colcon_ws/iinstall/localsetup.sh or $ _source ros2_docker/colconws/iinstall/setup.bash), and try $ _ros2 launch unity_slam_example unity_slamexample.py, the terminal shows: "ros2: command not found".

Or after I $ colcon build in the directory: ros2_docker/colcon_ws, and try $ _ros2 launch unity_slam_example unity_slamexample.py, the terminal also shows: "ros2: command not found".

My environment: Ubuntu 20.04, Ros2-foxy

Anyone could help me with this?

Thank you so much!

It succeeded after I tried $ source /opt/ros/foxy/setup.bash or $ source ~/ros2_foxy/ros2-linux/setup.bash first.
